Yes, Bill, you are just guessing. I, on the other hand, gave you some actual calculations with the example of Betelgeuse that I cited, to show you that a sufficiently large gas cloud will easily fit within its gravitational potential well — even though it might be so tenuous that on earth it would be considered a near vacuum.
Now can you give me some actual calculations to show that the repulsive forces you postulate would disperse a gas cloud before it can collapse to form a star?
Are you able to demonstrate how the mathematical models under consideration deviate from reality, and that the difference would be large enough to support your conclusions?
I take it that the astrophysicist that you cite refers to this article by Jason Lisle.
His article is, quite frankly, a joke. You only need to have used a bicycle pump to be aware that his claim that “gas is very resistant to being compressed” is bovine effluent. Similarly, his claim that “in space, there is no container” completely disregards the concept of gravitational potential wells — which, as an astrophysicist, he should fully understand. As for his other assertions, he does not cite any calculations whatsoever to back them up.
You claim you’ve studied physics yourself. In that case, you should be familiar with the instruction given to every student of the subject at a very elementary level: Show your working.
